Description

Survival plants of five varieties of orchardgrass (Dactylis glomerata L.) under grazing for four years at Shibetsu-cho in Hokkaido pref. ( 44°N, 50m), Iwadeyama-cho in Miyagi pref. (39°N, 52m) andAso-cho in Kumamoto pref. (33°N, 850m) were collected and their 13 characters were observed, comparing with those of the original varieties. Significant differences were found in many characters between the survivals and the originals and among the locations. Survivals ofKumamoto were found to be more different from the originals when compared with those of the other locations and were estimated to be useful materials for breeding a variety of persistency for the grassland in the mountain areas ( over 500m sea level) in the Southern Parts of Japan. Several characters were picked up for the selection of persistency under grazing in those areas.
